FIRE-EXTINGUISHER.

Specification of Letters Patent.

Application filed December 28, 1910.

Patented Nov; 21, 1911.

Serial No. 599,679.

To all whom it may concern:

Be it known that I, CHARLES H. DRIsooLL, a citizen of the United States, and a resident of Midvale, in the county of Salt Lake and State of Utah, have invented a new and Improved Fire-Extinguisher, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved chemical fire extinguisher, arranged to utilize the tank containing the solution and the acid receptacle as a reel for the hose, the nozzle of which normally engages a lock for holding the reel against rotation, whereby the acid bottle is held suspended in the tank until the latter is unlocked on removal of the hose and the tank is rotated on unwinding the hose.

For the purpose mentioned use is made of a revoluble tank for containing a solu tion, a fixed support extending within the tank for supporting an acid receptacle, and means in the tank and moving with the same when the tank is rotated, so'that the means push the receptacle off the fixed support on revolving the tank, to allow the contents of the acid receptacle to be discharged into the solution and thus produce the desired fire extinguishing fluid under pressure. A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. Figure 1 is a perspective view of the chemical fire extinguisher; Fig. 2 is an enlarged sectional side elevation of the same; and Fig. 3 is a sectional plan view of the same.

On a suitably constructed base A is erected a three-legged standard B, and a cylindrical tank O is journaled at its bottom by a step D on the base A, and the top of the. tank C is provided with a stufling box E,

through which extends a rod Fin axial alinement with the step D and adjustablysecured to a set screw F in the top connect ing arms of the standard B. Thus by the arrangement described, the tank 0 is held vertically disposed and mounted to turn on a vertical axis. The lower end of the rod F is provided with a sidewise-extending arm F on which rests the bottom of an acid bottle or receptacle G, extending with its upper portion into a short tube H held in the top of the tank C and extending to the outside thereof, the upper end of the tube H being normally closed by a cap H, which when removed permits removal of the receptacle G for filling the same with the desired acid and then returning the same to the tube H to reston the arm F The bottom of the receptacle G is connected by a chain or other flexible connection I with the arm F so that when the tank G is revolved and the tube H carries the receptacle Gr along it moves'the latter off the arm F so that the receptacle drops down in the tank C and by the chain I is held in upside down position to allow the contents of the receptacle G to flow out through the open top of the receptacle into the soda or carbonate solution contained in the tank C.

A fire hose J is coiled exteriorly around The lower coil of the hose J rests tom thereof, as plainly indicated in the drawings. The nozzle J 2 engages the hook :K of a locking pin K extending through an apertured arm C attached to the flange .C, the said pin K also engaging a cylindrical keeper K rising from the base A. Thus when the several parts are in the position shown in Figs. 1 and 2 the hose noz- 'zle J 2 engages the hook K of the locking pin K which now holds the tank C against accidental rotation; but when the nozzle J 2 is lifted then the pin K is likewise lifted and withdrawn from the keeper K and the arm C whereby the tank C becomes unlocked and cannow be revolved on pulling on the hose J with a view to-uncoil the same. Now when the tank C is rotated as described, by the operator pulling on the hose J, the

receptacle G is moved ofl' the arm F so that the receptacle finally drops within the tank G and: empties its contents into the solution to form afire extinguishing fluid under pressure, which passes out through the hose J and the nozzle J 2 to be directed onto the fire to be extinguished.

In order to prevent the hose J from accidentally uncoiling on the outside of the tank C use is made of a vertically-disposed roller L, journaled at its upper and lower ends at the middle of spring bands N, fastened at their ends to adjacent legs of the standard B, as plainly indicated in Figs. 1 and 3. The roller L presses the outermost layers of the hose J so as to hold the hose against accidental uncoiling, thus maintaining the hose in proper coiled position and preventing entangling of the hose when unwinding the same from the tank C.

The fire extinguisher shown and described is very simple and durable in construction, and provides convenient means for holding the solution and the acid employed for forming a fire extinguishing fluid, and also for accommodating the hose J in a simple and compact manner.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A fire extinguisher, comprising a revoluble tank for containing a solution, a fixed support extending within the tank, an acid receptacle resting 011 the said support, means in the said tank and moving with the same, for engaging the said receptacle tomove the latter off the fixed support on revolving the tank, and a flexible connection between the said fixed support and the said receptacle.

2. A fire extinguisher, comprising a revoluble tank for containing a solution, a fixed support extending within the tank, an acid receptacle resting on the said support, means in the said tank and moving with the same, the means engaging the said receptacle to move the latter off the fixed support on revolving the tank, a hose adapted to be wound on the outside of the said tank and having one end connected with the interior of the tank, the other end of the hose carrying a nozzle, and a locking device engaged by the said hose nozzle for locking the tank against turning.

V 3. A fire extinguisher, comprising a revoluble tank for containing a solution, a fixed support extending within the tank, an acid receptacle resting on the said support, means in the said tank and moving wit-h the same, the means engaging the said receptacle to move the latter off the fixed support on revolving the tank, a hose adapted to be wound on the outside of the said-tank and having one end connected with the interior of the tank, the other end of the hose carrying a nozzle, and spaced spring bands fixed at the ends and having a friction roller extending between the bands at their middle and pressing the said hose.

4. A fire extinguisher provided with a revoluble tank, a hose coiled exteriorly on the said tank and having one end connected with the interior of the tank, spaced spring bands fixed at the ends, and a vertically-disposed roller journaled on the said spring bands and engaging the coils of the said hose.

5. In a fire extinguisher, the combination of a revoluble tank, a hose communicating therewith and coiled exteriorly thereupon for the purpose of turning said tank as said hose is unwound therefrom, a stationary member mounted within said tank, a receptacle adapted to hold acid and normally supported by said stationary member, and means controllable by the revolution of said tank for upsetting said receptacle and liberating said acid from said tank.

6. In a fire extinguisher, a revoluble tank for containing a solution, a hose connected with the tank and adapted to be coiled thereon, a stationary support extending into the tank, an acid receptacle on the support, and a member secured to the tank and engaging the receptacle to move it OK its support when the tank is revolved.

7 In a fire extinguisher, a revoluble tank for containing a solution, a hose connected with the tank, an acid receptacle, a stationary support extending into the tank and upon which the acid receptacle is supported, and an annular member carried by the tank and into which the acid receptacle projects when above the said support.

8. In a fire extinguisher, a revoluble tank provided with a tube projecting through its top and having a removable closure for its outer end, a hose connected with the tank, a stationary support extending into the tank and normally below the tube thereof, and an acid receptacle on the support and projecting into the tube of the tank.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
